The MURI team has reported for the first time sub-terahertz spin pumping at the interface of the uniaxial insulating antiferromagnet manganese difluoride and platinum. The measured ISHE voltage arising from spin-charge conversion in the platinum layer depends on the chirality of the dynamical modes of the antiferromagnet, which is selectively excited and modulated by the handedness of the circularly polarized sub-terahertz irradiation. Our results open the door to the controlled generation of coherent, pure spin currents at terahertz frequencies.
